Yeah, destructive testing is still a must for process checking. Though non destructive methods for even composites keep getting better! Composites are very very hard to test though, and I think it's one of the biggest bottleneck to their usage. (I work in NDT(non destructive testing) but on the software stack not the probes/scanners. So I'm not sure if my last point is still true these days! )
